Welcome to Sequoia Scientific, Inc.

In 1995, Sequoia Scientific, Inc. introduced the world’s first submersible commercial instruments for particle intelligence (particle sizing, concentration, imagery and optical properties) based on laser diffraction – LISST. The brand name LISST derives from Laser In-situ Scattering and Transmissometry. LISST systems are self-contained, compact, programmable, battery-powered, and they hold calibration for life. Instruments using holography and acoustic backscatter have subsequently been introduced under the LISST brand. We offer a condensed view of the entire instrument line by application below.

Reservoir Siltation and River Sediment Transport

In addition to all of the above instruments, the following is specific for rivers:LISST-SL2 Replacement for point-integrated or depth-integrated samplers. Profiles river columns for PSD, Concentration, Depth, Temperature, and velocity.
